LAMP-WICK.

SPECIFICATION forming part of Letters Patent No. 399,277, dated March12, 1889.

Application filed April 7, 1888.

T0 all 1071.071@ 'it mf/y] con/c0770:

lie it known that I, AUoUs'r MUELLER, of Kansas City, Jackson county,Missouri, have invented a new and useful Improvement in Lamp-ll'icks, ofwhich the following' is a full, clear, and exact description, referencebeing had tothe accompal'iying drawings, formii'lg a part hereof.

My invention relates to tubular lamp-wicks, andhas for its object to providea more cheap, simple, and effective wick than has heretofore been inuse.

\Vith these ends in view myii'lvention consists in the peculiar featuresand arrangement of parts more fully described hereinafter, and pointedout inv the claims.

Referrii'lg to the aceomlianying drawii'igs, Figure l.l is a sectionalelevation of a centerdraft lamp provided with my improved wick, and Fig.2 is a perspective of the wick applied to the center tube of a lamp.

The refererice-letter A indicates the upper portion of my wick, and maybe formed integral with the lower portion, or may be sewed or otherwisesecured thereto. This upper section, A, is made tubular, and is adaptedto slide upon the center tube of the lamp by means of any suitableraising and lowering dcyice. The remainder of the wick consists of theslit portion 1:3 and the lower tubular section, l). The portion l isslit longitudinally, and thus divided into a number of strips, ll',which connect the upper and lower tubular sections of the wick.

The operation of my device is as follows: The wick is placed upon thecenter tube of the lamp, with the lower tubular section, l, around thebottom of said tube. The upper portion, A, is then slid downward untilits top registers with the upper extremity of the center tube, thuscausing the several strips "3 to diverge from the center tube and spreadover the bowl of the lamp. The lamp is'then filled with oil, and as thewick burns the upper portion, A, is slid upward by any suitable means;but the lower section, Z1, always remains at the bottom of the tube.lVhen the wick has been used until the lower extremity of the upperportion, A, reaches the top of the center tube, a new upper portion isattached and slid down upon the eenter tube, and the operation justdescribed is repeated. Thus by employing my device all the oil in thebowl of a lamp is used lup bei fore refilling becomes necessary, for thereai Serial No. 269,903. (No model.)

son that the lower extremity of the wick always remains at the bottom ofthc bowl of the lamp.

The advantages of this form of wick are: As the wick is slitintermediate of its upper and lower extremities, it iiaeilitates placingthe same in the lan1p,because thelower tubular portion can be moreeasily slid down over the central tube, whereas in wicks where thestrips are disconnected at their lower ends the operator would beobliged to grasp all of them in his hand and hold them together whileinserting the wick into the lamp. In my construction the lower end ofthe wick will always reston the bottom of the bowl of the lamp by reasonof the friction between the wick and the central tube. The strips willdiverge uniformly from the central tube of the lamp, and therefore feeda more regular and full supply of oil to the upper portion, as found byactual"'usc. Besides producing these beneficial results, the wickpresents a finished, symmetrical, and ornaniental appearance when inuse. The wick being constructed in the manner described greatly:facilitates packing, shipping, and handling of the same, as it can bereduced to the form of a flat wick and packed in a Very small com pass.It can be more cheaply manufactured, as it is slit intermediate of itsupper and lower extremities, and consequently the ends of the strips donot rcquirebinding to prevent them from unraveling.

ll avin g thus described my invention, what I claim as new, and desireto secure by Letters Patent, is-

l. A lamp-wick composed of a pair ol' tubular sections connectedtogether by separated longitudinal strips, inthe manner and for thepurpose described.

2. In a tubular lamp-wick, the combination of an upper tubular sectionadapted to slide upon the center tube of a lamp, a lower tubular sectionadapted to remain stationary at the base of said center tube, andseparated longitudinal strips connect-ing said upper and lower tubularsections, in the manner and for the purpose set forth.

In testimony whereof l afiix my signature in presence of two witnesses.

AUGUST MUELLER.
